NEW YORK & LONDON--(BUSINESS WIRE)--OpenGamma,
creators of the first open source analytics and risk management platform
for the financial services industry, today announced the appointment of
Mas Nakachi as Global COO and CEO of North America. OpenGamma continues
to invest in its senior management team, bringing on top industry talent
to strengthen service delivery, enhance local client support and
capitalize on the growing global demand for the OpenGamma
Platform.

“The demand we are seeing for the OpenGamma Platform highlights the
belief we held from our first vision of OpenGamma: that the industry
needs a new standard for risk analytics”

Nakachi joins OpenGamma’s senior management team from Calypso
Technology, where he was most recently director
of business development for the rates, fixed-income and credit
business. In this position, Nakachi was responsible for ecosystem
development, marketing, client support and new product development
initiatives, as well as strategic client acquisition for Calypso’s
largest business solution segment. He previously served as Calypso’s
director of strategy and corporate development, and began his career
developing and growing Calypso’s credit derivatives business,
establishing it as a number one ranked solution, as acknowledged by
numerous industry publications. A recognized expert and industry thought
leader on credit derivatives, structured finance and OTC derivatives
market structure, Nakachi brings over a decade of proven experience to
his role at OpenGamma. Based in New York, he will oversee the company’s
North American operations and work with the London-based executive team
to manage all operational areas of the business.

Nakachi’s recruitment follows several recent high-profile OpenGamma
appointments, including the addition of Hugh Stewart as global head of
sales. Stewart brings more than three decades of global financial
services and technology experience to the OpenGamma executive team,
including demonstrated success growing start-ups and significantly
increasing sales for established enterprise software firms. Prior to
joining OpenGamma, Stewart most recently served as sales director at
SmartStream Technologies. Throughout his career, he has held senior
business development and leadership roles at global firms, including his
tenure as Managing Director at Bankers Trust, C*ATS Software,
Algorithmics and QuIC Financial. These executive appointments underscore
OpenGamma’s continued success and maturing business model, as the firm
leverages its recent $15 million Series
C funding round led by ICAP plc to bring on key personnel, drive
continued product innovation and accelerate client and geographic growth.

“OpenGamma continues to invest in our people, our product innovation,
and our growing open source community as we work to democratize and
radically change the levels of transparency related to risk analytics
within capital markets,” said Kirk Wylie, Co-founder and CEO of
OpenGamma. “Mas and Hugh both offer invaluable industry knowledge and
proven experience, and share our vision and enthusiasm to change how
firms view their risk infrastructures, navigate today’s volatile
regulatory environment, and access and deploy the most cost-effective,
powerful risk analytics tools available.”

2012 has been a landmark year for OpenGamma, beginning with the launch
of the OpenGamma Platform 1.0 in April. This was followed quickly by the
company’s recognition as the winner and “Top Innovator” at the Innotribe
Startup Challenge held in Belfast, honoring the company as one of
the most promising financial technology and financial services start-ups
and earning them a trip to the Innotribe Startup Challenge Finals at Sibos,
SWIFT’s annual conference, in Osaka, Japan. OpenGamma was also selected
as one of Risk Magazine’s Firms
of the Future, a select group of organizations forecast to have the
biggest impact on the OTC derivatives market over the next five years.
Building on this success, OpenGamma recently announced their $15 million
Series C round of equity financing led by ICAP plc and joined by Euclid
Opportunities, with follow-on investments from previous investors Accel
Partners and FirstMark Capital.

“The demand we are seeing for the OpenGamma Platform highlights the
belief we held from our first vision of OpenGamma: that the industry
needs a new standard for risk analytics,” said Mark Beeston, Chief
Executive Officer for ICAP’s post trade and risk mitigation businesses
and member of OpenGamma’s Board of Directors. “OpenGamma’s ability to
attract executives of Mas and Hugh’s caliber is a testament to the
company’s truly disruptive business and technology model, recognized
innovation, and the collaborative community they’ve created that will
usher in a new era for financial services technology.”
